Using Fray does not require knowledge about "deterministic testing" or "controlled concurrency." This is one of its goals: developers write normal concurrency tests, and Fray controls the execution behind the scenes.

In fact, when we evaluate Fray, we collect all existing concurrency tests from Lucene, Kafka, and Guava, and running them under different thread inter-leavings can already reveal so many bugs. [1]

Writing good “normal” concurrency tests is hard is what I’m saying. I get that it slots in well with existing tests that are already written.
